For anyone that uses mobile free-standing squat stands, they can be placed back-to-front further down the bench, at the point where the arms would be in extension and that permits the load to be taken from the stands without a spotter.

Placing a low "catch" item (aka safety bars, stacked books etc) each side, below the head (lowest point the EZ bar will reach to) in case the last rep is just too much to return to the starting point.
